SELF-LEVELING GRADUATING MEASURING-GLASS AND HOLDER.

SPECIFICATION forming part of Letters Patent No. 575,033, dated January12, 1897.

Application filed May 4, 1896. Serial Nox 590,147. (No model.)

To aZZ whom it may concern:

Beit known that I, J AMES IILEHMANN, a citizen of the United States, anda resident of New York, in the county and State of New York, haveinvented a certain new and useful Self-Leveling GraduatingMeasuring-Glass and Holder, of which the following is a speoification.

My invention relates to graduating measuring-glasses employed bydruggists in determining the correct quantity of fluid ingredients incompounding prescriptions.

Heretofore graduating-glasses have been constructed with a foot orprojecting base integral with the glass and serving to support the samein an upright position when resting on a table or counter. The foot orbase being of glass is often broken off in use, and when this occurs theinstrument for many purposes is rendered unserviceable; and in theaccurate measurements of quantity the instrumentmust rest uponaperfectly level surface, which is not always available.

The object of the present invention is to furnish a graduatingmeasuring-glass free from the objections above mentioned and which willbe self-leveling.

The invention is shown in the accompanying drawings, in which- Figure 1is a View in elevation of my graduating measuring-glass and its holder,and Fig. 2 a similar view at right angles to Fig. 1.

In both views the same numerals are used to indicate the same parts.

Referring to the drawings, 3 indicates a stand or holder comprising anextended fiat base or foot 5and a pedestal 5 from the top of which risea pair of standards 4, which curve outwardly from the pedestal and areprovided at their tops with the inwardly-extending parts 6, the topsurfaces of which are formed with knife-edges, as shown best in Fig. 2.The

stand 3 will preferably be made of metal, and its base 5 will besufficiently heavy to firmly sustain the stand in an upright position.

The measuring-glass 7, which tapers to a point, or to such an extent asnot to be adapted to stand safely on its own bottom, is'provided, asshown, with the usual graduations and has an outwardly-curved lip and aspout 8. I11 addition, I form the glass 7, in the process of making thesame, with the ears or lugs 9, having in their bottom grooves or slots10, preferably inverted-V shaped, whose bottom surfaces are curved orrounding, as shown clearly in Fig. 2.

The measuring-glass 7 is adapted to be supported by the lugs 9 upon theknife-edges 6 of the standards 4 of the stand, as shown in the drawings,and when placed in the supporting-stand it will assume and maintain aperpendic ular position, whether the stand 3 rests upon a perfectlylevel surface or not. Aside from the advantages incident to theemployment of a measuring-glass and stand constructed as explained thereis an advantage in having a fixture for the glass when not in use whereit is protected from breakage and may always be found when needed.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of a druggists or similar glass havinginverted-V-shaped lugs 011 opposite sides near its top, and a base andpedestal with standards the ends of which bend inward and engage saidlugs from the lower side, whereby the glass takes a vertical position,and is free to be lifted from the standards.

2. The combination of a graduated druggists or similar glass tapering toa point at itsLlower end, inverted-V-shaped lugs near the top of theglass, and a base with standards engaging the lugs, whereby the glasshangs freely, and is free to be lifted from the standards.

Signed at New York, in the county and State of New York, this 1st day ofMay, 1896.
